Application led January 9, .1922. Serial No. 527,896.

T 0 all whom may concern.'

Be 1t known that l, OswALD SoHiAUPITz,

a citizen of the United States, and a resi-V dent of the city of Canton, in the county of Stark and State of Ohio, have invented a new and useful Improvement in :indicating Gauges, of which the following is a specification.

This invention relates to internal indicating gauges and has for its principal object to produce a gauge that'will determine the diameter and the contour and parallelism of the surfaces of circular cavities or perforations, such as the cylindrical bores of inner bearing members for roller bearings Another object is to simplify the gauging operation. Another object is to simplify the construction of the gauge and to reduce the cost thereof- The invention consists in the hereinafter described means for attaining the above objects; and it also consists in the parts and combinations of parts hereinafter described and claimed.

'In the accompanying drawings, which form part of the specification and wherein like symbols refer to like parts wherever they occur, Y

Fig. l is a front elevation of an indicating gauge embodying my invention;

Fig. `2 is a vertical section through said gauge, an inner bearing member for a roller` bearing beingv shown `mounted thereon in position to be gauged;

. Fig. 3 is a rear elevation of the gauge with the rear cover plate removed; and

Fig. 4 is an axial section through the supporting member of the gauge on the line 4-4 in F ig. 1. y

The gauge shown in the accompanying drawings comprises anv upright casing or housing 4 having a base portion 6 which is perforated for the reception of bolts or similar securing devices whereby the casing may be rigidly secured to a work bench, Y Projecting horizontally from the front face 5 Y l --for vertical swinging movement 1n the plane of the casing 4 yis a cylindrical work receiving and supporting member 7 having an axial bore 8, whose inner end communicates with the interior of said casing through an opening 9 in the front wall thereof.

Located within the axial bore 8 of lthe supporting member 7 and extending rearwardly into the interior of the casing 5,'

is a lever arm 10. The lever arm vl0 vis produced width midway -within the notch 11 of the lever arm 10 formed in the front end ofthe lever arm 10. The lever arm 10 is pivotally secured vided at its front end with an elongated vertical notch. 11 adapted to receive a vertically disposed cylindrical contact pin 12 anda horizontally disposed cylindrical fulv Crum stud 13. The contact pin 12 is of reof its length to fit and is removably held therein by means of a horizontal screw 14. The contact pin'12 has a free sliding fit in a transverse bore in the supporting member 7, said bore being disposed with its axis vertical and intersecting the" horizontal bore 8 at aV point substantially midway of its length.

The fulcrum stud 13 is mounted inthe axial bore 8 of the supporting member 7, between the gauge pin 12-v andthe front end of said member, and has a reduced portion adapted to be embraced by the notch 11 to the fulcrum stud 13 by means of a re movable pivot screw 15, which extends horizontally through the intertting portions of said lever arm and said stud. The hollow supporting member is provided with holes 16, which extend horizontally through one side thereof whereby the screws 14 and 15 may be readily inserted and removed. The contact pin isadapted to contact with the surface of the work at its lower end only,

'and said 'end is preferably Vcurvedto conform7 to the radius of the supporting member The free end of the lever arm 10, in the inoperative position thereof, is supported on the upper end 'of a vertical stop-pin 17. The stop l17 has a` threadedhead portion which is threaded through the base of the casing 4- for purposes of adjustment The 9 free end of the lever arm 10 is held against horizontal movement by means of guide screws *18, which `are threaded through the side walls ofthe casing in axial alinement and engage the lever on opposite sides.

Located within the-casing 4, and arranged of the lever arm 10,*is a lever 19, which has a segment gear 2O formed on its upper end and is provided at its lower end with a hori- 105 zontal spindle`21. llhe spindle 21 projects on opposite sides of the lever 19 and is rotatably supported above the lever arm10, `adjacent to the free end thereof, by means of alined pivot screws 22, which are'threaded 110 replaced with similar members of different sizes, thereby adapting the gauge `for use with articles having bores of different dialneters.

What I claim is:

l. A gauge comprising a hollow cylindrical work receiving member, a pivot member transversely disposed in said support, a lever arm pivoted at one end on `said pivot member. an indicating mechanism operatively connected with the free end of said lever arm to be operated thereby, and a work engaging element projecting from said lever arm between the pivot therefor and the free end thereof, said work engaging element extending at right angles to said lever arm pivot.

2. A gauge comprising a casing having a hollow cylindrical work support, said support having a transverse opening, a pivot member transversely disposed in said support, a lever arm extending axially of said support and having one end fulcrumed on said transverse pivot, an indicating deviceV mounted in said casing and cooperating with the free end of said lever to be actuated thereby, and a gauge pin projecting from said lever arm between the pivot therefor and the free end thereof, said gauge pin extending at right angles to the lever arm pivot and working in the transverse opening in said work support.

3. A gauge comprising a casing having a hollow cylindrical work support, said support having a transverse opening, a pivot member transversely disposed in said support, a lever arm extending axially of said support and having one end `fulcrumed on said transverse pivot, an indicating devicel mounted in said casing and cooperating with the free end of said lever to be actuated thereby, and a guage pin projecting from said lever arm between the pivot therefor and the free end thereofj said gauge pin extending at right angles to the lever arm pivot and working in the transverse opening in said work support. said work supporty and said gauge pin being detachably secured to said casing and said lever arm respectively. whereby said members are adapted to be replaced by similar members of different sizes.

il.
